To add a header image to a submission form, open the project → Form Builder → Design → Header Image, then upload a PNG or JPEG. The header appears as a banner at the top of the form and is the first thing creators see. Use a 3:1 ratio image (recommended 1800x600px) so it looks crisp on every screen size.
Why add a header image?
Adds brand recognition — creators see your logo or imagery before reading any field.
Creates a clean banner-style layout that anchors the form visually.
Adds legitimacy — a branded form looks more professional than a default one.
Keeps branding visible without taking up too much vertical space.

How to add a header image
Open the project → Form Builder.
Open the Design & Settings tab.
Click Header Image.
Click Change and choose a PNG or JPEG from your device.
Save.
Each project's form can have its own header image, so different programmes can carry different visuals.

Best practice for header images
Avoid embedding text directly in the image — assistive tech can't read it, and it looks fuzzy on retina displays.
Use a horizontal image — vertical images get cropped awkwardly.
Compress before uploading. A 3 MB image will slow your form on mobile.
Test on mobile after uploading — the header crop point shifts on narrow screens.
